Definitions

  • the invention relates to a mineral fiber insulating body, in particular a molded part, made of mineral fibers bound with binder in felt or plate consistency or in shell form, according to the preamble of claim 1, as well as products produced herewith or here in the form of a pot-shaped part according to the preamble of claim 5, one Composite component according to the preamble of claim 7 and a mineral fiber insulation shell according to the preamble of claim 9.
  • Mineral fiber products for sound and / or thermal insulation are mainly manufactured as sheets, plates or shells. These products are also well suited for many areas of application, since they may only need to be cut to size. However, if uneven surfaces or complicated bodies are to be insulated with this, considerable effort may be required to adapt these products to the desired shape.
  • multi-layer insulation layers are therefore often used in order to obtain corresponding overlaps at joint points, or a step fold is introduced into a single-layer insulation layer by milling, for example. Moldings are often required chen, which are produced as stampings and require such considerable mold costs - for complicated body and F LAE.
  • the invention has for its object a thermal insulation body of the type specified in the preamble of claim 1 and special, hereby or hereby manufactured products according to the preamble of To create claims 5, 7 and 9, in which an adaptation to the dimensions and shapes of surfaces or bodies to be insulated in individual cases can be done easily and without material loss for many applications.
  • the material area intended for the formation of the recess is thus delimited from the surrounding material by one or more incisions and, if necessary, its compressibility is improved and the depth of the intended recess is separated, so that the material separated in this way in the area of the intended recess for its formation can be easily compressed. Only relatively small forces are required for this, depending on the consistency of the mineral fiber material, of course, since the deforming action is actually limited to the limited area of the depression due to the incision limitation and, if necessary, is facilitated by additional internal incisions, particularly in the case of large depressions in shell surfaces.
  • the incision limitation of the depression prevents deforming entrainment of surrounding material areas.
  • Such surrounding material areas can, however, be deformed separately, if necessary, to different extents, whereby interactions due to the incision boundaries between the individual material areas are excluded.
  • the mineral fiber material is then compressed in relation to the starting material, which is the case for certain users cases is advantageous.
  • the compressed mineral fiber material tends to spring back at the bottom of the depression, which is also frequently desired, for example in order to achieve a tight fit even if the dimensions are inaccurate.
  • the incision advantageously extends transversely to the main orientation direction of the fibers. It is thereby achieved that the compression of the mineral fiber material takes place predominantly by mutual proximity of adjacent fibers and only to a lesser extent by kink loading and thus breakage of fibers lying in the loading direction. Since such mineral fiber products generally have fibers oriented parallel to the surface, the implementation of this measure generally does not pose any additional problems if the incision runs vertically into the material from the surface, which in turn is the rule for most applications.
  • the incision is preferably made in relation to the depth of the one to be produced. Deepening led to greater depth. In this way, on the one hand, the production of a deepening of the bearing of variable depth depending on the circumstances of the individual case is made possible without any problems, since even in cases of somewhat greater depth there is no fear of the compression movement being impeded by the holding effect of adjacent, non-separated material parts.
  • the incisions can easily be made mechanically in the course of production or in the course of subsequent assembly, taking into account the circumstances of the individual case, for example by hand with a knife.
  • a mineral fiber insulation body provided by the manufacturer with an incision is functionally fully operational even if no indentation is actually created at the incision, since the incisions can be kept extremely narrow, barely visible and there is no removal of mineral fiber material at this point with their introduction.
  • This additional advantage of the invention compared to milling out or the like can in particular also be used according to claim 4 to make a plurality or a plurality of incisions at the manufacturer's sites where there is only one possibility for a later need to form a recess.
  • the incisions can be made according to a certain pattern, for example in parallel rows or in a rectangular pattern, and, in use, those fields between the incisions can be selectively deformed by compression to form a depression, where this is necessary, while other fields despite the cuts of deformations present there remain unaffected.
  • the types can be limited to a certain specific pattern, certain incision distances or certain grating widths or the like in the case of stockpiling, and for the variable application in each case it is only selected which of the prefabricated patterns best meets the needs of the application.
  • the subclaims 6, 8 and 10 have advantageous developments of the pot-shaped part according to claim 5 or the composite component according to claim 7 or the thermal insulation shell according to claim 9.
  • a mineral fiber insulation body designated by 1 according to FIG. 1 may be present in the example in the consistency of a relatively dimensionally stable plate.
  • the mineral fiber insulation body 1 is intended to accommodate a component 2 in the installation position in the form of a threshold in a recess 3 in the example case.
  • the threshold is provided on one of the two rigid boundary walls labeled 4 and 5, between which the mineral fiber insulating body 1 is to be inserted.
  • an incision 6 and 6a is made in the surface of the insulating body 1 in the edge region of the recess 3, which can be done either by punching during the course of manufacture or assembly, or subsequently, if necessary, using a suitable cutting tool such as a knife or a fox tail .
  • a suitable cutting tool such as a knife or a fox tail .
  • the mineral fiber material is compressed on the front side of the component 2 between the incisions 6 and 6a when the insulating body 1 is installed between the rigid boundary walls 4 and 5, so that the component 2 forms the recess 3 can penetrate the mineral fiber material.
  • the cuts 6 and 6a on both sides prevent any interference with the adjacent material.
  • the mineral fiber material in the base of the recess 3 only provides limited resistance to the penetration of the component 2, since it can move independently of the mineral fibers that are adjacent on the side.
  • the cuts 6 and 6a are made at a depth T exceeding the depth t of the recess 3, the cuts 6 and 6a extend into a material region at a distance from the bottom of the recess 3, in which the compression is only slightly effective , so that the lateral connection there to the surrounding mineral fibers is harmless as a result of the felting and the binder present. Since the mineral fiber material tries to spring back in the base of the recess 3, the insulating body 1 is at the same time pressed against the opposite boundary wall 5 with a predetermined pressure.
  • the mineral fiber insulation body 1 In the event that the mineral fiber insulating body 1 is already prepared for receiving the component 2 by making the incisions 6 and 6a, but the component 2 is actually not present at the installation position in an individual case, there are no functional disadvantages; because then the mineral fiber insulation body 1 lies in the configuration shown in FIG. 1 between the boundary walls 4 and 5 and is thus available over its entire surface without loss of insulation capacity Available. Even when the mineral fiber material is compressed by the component 2 with the formation of a corresponding recess 3, the thermal or acoustic insulation capacity of the mineral fiber material in the region of the component 2 does not suffer, or does not suffer appreciably, since no material loss is associated with the formation of the recess.
  • Panel or sheet-shaped mineral fiber insulation bodies 1 made of mineral fibers bound with binder are generally produced on continuous production lines in such a way that the mineral fibers are deposited on the web after they have been produced and then subjected to further effects such as compaction, heating, cuts, etc. at work stations passed through by the web .
  • a main orientation of the fibers is established, which is essentially parallel to the support surface of the production line and to a certain extent also in the direction of production, so that the fibers are to a large extent approximately parallel to the surface.
  • FIG. 5 illustrate a special application of the invention for producing a composite component 10, as is used, for example, for the thermal insulation of heat storage devices.
  • the composite component according to the invention illustrated in FIG. 5 consists of two plate-shaped mineral fiber insulating bodies 11 and 11a, one of which is not shown in greater detail on both sides provided heat storage and are connected on the end face by a component 12, which in turn is a mineral fiber insulation body.
  • FIGS. 3 and 4 A problem here is that in order to achieve the required tightness in the dimensional tolerances of the mineral fiber plates occurring in the connection areas, a stepped rabbet connection must be used. This can, of course, be produced in the manner shown in FIG. 3 simply by providing the side edges of the mineral fiber boards which abut one another, as is also known for other materials in such a joint area, for example by milling with steps. In order to avoid such processing, the solution shown in FIG. 4 is then adopted, in which the individual insulation layers are designed in two layers, and a step-like configuration is achieved without milling or the like by corresponding mutual arrangement of the individual layers shown in FIG. 4.
  • the described problem within the scope of the invention can be easily solved by making incisions 16 and 16a in the mineral fiber insulating bodies 11 and 11a in the manner shown in Fig. 5, in which the thermal insulation material there Formation of wells 13 and 13a is compressible without disturbing adjacent material parts.
  • the component 12 in the form of the end plate is then simply inserted between the recesses 13 and 13a formed in this way by a suitable tool and resiliently clamped in the region of the recesses 13 and 13a to form a defined step fold when the compressed material springs back.
  • the mineral fiber plates for forming the mineral fiber insulating bodies 11 and 11a and the component 12 can have the usual thickness and constant formats; it is only necessary to make the incisions 16 and 16a according to the principles explained in connection with FIGS. 1 and 2 in order to obtain a composite component 10 according to the invention.

  • the annular surface outside of the annular incision 26 is covered by an upper ring flange 28 of the shell-shaped component 22, so that the component 22 can be attached to the housing 24 or to the flange 25 thereof, the housing 24 thus serving as a counter-holder for the component 22.
  • an electrical heating winding 29 is arranged on the bottom of the shell-shaped component 22, which can serve for heating a medium to be arranged in the pot recess 27.
  • the compression of the mineral fiber material present in the example in felt consistency at the bottom of the depression 23 has an advantageous effect.
